In the embodiment, the connector 40 is a Registered Jack-45 (RJ-45) connector. The connector 40 includes a connecting portion 41, and a cable 43 connected to the rear end of the connecting portion 41. A step surface 412 facing forward is formed on a middle of the top of the connecting portion 41. A resilient tab 415 slantingly extends down from the bottom of the connecting portion 41.
The assisting apparatus 10 includes a hollow first rotatable member 20 and a second rotatable member 30.
The first rotatable member 20 includes two opposite first sidewalls 21, a first top wall 23 perpendicularly connected between front sections of the tops of the first sidewalls 21, and a first bottom wall 25 perpendicularly connected between rear sections of the bottoms of the first sidewalls 21. The first bottom wall 25 is substantially parallel to the first top wall 23. A cutout 211 is defined in each first sidewall 21 above the first bottom wall 25. A pivot hole 214 is defined in each first sidewall 21, adjacent to a middle of the bottom of the first sidewall 21. A notch 212 is defined in the bottom of each first sidewall 21 between the corresponding pivot hole 214 and the first bottom wall 25. A section of the bottom of each first sidewall 21 in front of the corresponding notch 212 gradually slantingly extends up. A supporting portion 215 (see FIG. 4) protrudes inwards from a lower section of the inner surface of each first sidewall 21, parallel to the first top wall 23. The supporting portions 215 are respectively arranged above the pivot holes 214. A through slot 27 is defined in each of the first top wall 23 and the first sidewalls 21. The through slots 27 of the first sidewalls 21 are respectively arranged above the supporting portions 215. Each of the first top wall 23 and the first sidewalls 21 forms a resilient latch 271 extending rearwards from a section adjoining the front end of the corresponding through slot 27. A latching portion 237 extends into the corresponding through slot 27 from the rear end of each latch 271. A stop plate 29 extends down from the front end of the first top wall 23.
The second rotatable member 30 includes an elongated abutting portion 31. The abutting portion 31 includes a second bottom wall 312, and two flanges 313 respectively extending up from two opposite sides of the second bottom wall 312. A resilient arm 315 slantingly extends down from the second bottom wall 312, adjacent to the rear end of the second bottom wall 312. The outer surface of each flange 313 forms a pivot 316 adjacent to a middle of the flange 313, and a block 317 between the pivot 316 and the resilient arm 315. A second sidewall 33 extends out and up from a rear section of the top of each flange 313. A second top wall 35 is connected between the tops of the second sidewalls 33.
Referring to FIGS. 4 and 5, to assemble the connector assembly, the front end of the abutting portion 31 is inserted into the first rotatable member 20 from the rear side of the first rotatable member 20, with the front end of the abutting portion 31 arranged below the supporting portions 215. The pivots 316 are respectively rotatably engaged in the pivot holes 214. Thereby, the second rotatable member 30 is rotatably connected to the first rotatable member 20. The assisting apparatus 10 is assembled. The resilient arm 315 abuts against the top surface of the first bottom wall 25, to drive the second rotatable member 30 to rotate and form an angle between the abutting portion 31 and the first bottom wall 25. The rear end of the abutting portion 31 is tilted up relative to the first bottom wall 25, and the front end of the abutting portion 31 is tilted down relative to the first top wall 23. The second sidewalls 33 are respectively received in the cutouts 211, and the front end of the second top wall 35 engages with the rear end of the first top wall 23. The first and second rotatable members 20 and 30 bound a receiving space 15 (see FIG. 1). The blocks 317 are respectively received in the notches 212. When the rear end of the second rotatable member 30 is rotated upwards relative to the first rotatable member 20, the blocks 317 can engage with the portions of the first sidewalls 21 adjoining the tops of the notches 212, and prevent the second rotatable member 30 from overly rotating upwards.
The second top wall 35 is pressed down relative to the first rotatable member 20, to allow the rear end of the second rotatable member 30 to rotate downwards, and to allow the front end of the second rotatable member 30 to rotate upwards. The resilient arm 315 is deformed. When the bottoms of the second sidewalls 33 abut against the tops of the rear sections of the first sidewalls 21, the second bottom wall 312 is substantially parallel to the first top wall 23 and the first bottom wall 25. The connecting portion 41 is inserted into the receiving space 15 from the rear side of the assisting apparatus 10, with the bottom of the connecting portion 41 supported on the supporting portions 215. The latching portions 273 abut against the connecting portion 41, with the latches 271 deformed outwards. When the step surface 412 abuts against the stop plate 29, the latches 271 are restored to allow the latching portions 273 to engage with the rear end of the connecting portion 41. Thereby, the connector 40 is fixed to the first rotatable member 20. The front end of the connecting portion 41 is exposed out of the front end of the first and second rotatable members 20 and 30. The resilient tab 415 abuts against the front section of second bottom wall 312 and is deformed upwards.
When the second rotatable member 30 is released, the resilient arm 315 is restored to push the rear end of the abutting portion 31 to rotate upwards relative to the first bottom wall 25. The front end of the abutting portion 31 is rotated downwards to make the resilient tab 415 be restored.
Referring to FIGS. 1 and 2, to plug the connector 40 in the electronic device 50, the rear ends of the first and second rotatable members 20 and 30 are rotated towards each other, to allow the resilient arm 315 to be deformed. The front end of the abutting portion 31 is rotated towards the first top wall 23, and the resilient tab 415 is deformed. The front end of the connecting portion 41 is inserted into the connector socket 512. The rear ends of the first and second rotatable members 20 and 30 are released, and the resilient arm 315 is restored to push the rear end of the abutting portion 31 to rotate upwards, and allow the front end of the abutting portion 31 to rotate downwards. The resilient tab 415 is restored downwards and engages in the latching slot 513. Thereby, the connector 40 is fixed to the connector socket 512.
To unplug the connector 40 from the connector socket 512, the rear end of the second rotatable member 30 is pressed towards the first rotatable member 20. The front end of the abutting portion 31 is rotated upwards and deforms the resilient tab 415, to allow the resilient tab 415 to disengage from the latching slot 513. The assisting apparatus 10 is pulled away from the electronic device 50. The connecting portion 41 can be detached from the connector socket 512.
Even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and the functions of the embodiments, the disclosure is illustrative only, and changes may be made in details, especially in matters of shape, size, and arrangement of parts within the principles of the embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
